📄️ NFT Collection Volume
This metric tracks the gross HBAR paid (in tinybars) for specified NFT collections over defined time periods. It measures positive HBAR value moved in transactions that transfer NFTs, excludes treasury self‑payments, and proportionally allocates per‑transaction HBAR across all NFTs moved so bundle sales are handled correctly.
📄️ NFT Collection Volume (Total)
This metric tracks the total gross HBAR volume attributed to NFT collections on the Hedera network. It sums positive HBAR transfers from transactions that include NFT movements and excludes any positive HBAR paid to treasuries of tokens moved in that transaction; the remaining HBAR is then allocated proportionally to each collection by its share of NFTs moved in the transaction (splitting the bill by item count).
